You can go to vCenter and deploy the senso OVA using this URL:

https://<faddom-server>/Installations/Sensors/Template/Faddom-Sensor-Appliance-2021.4.9.ovf

Just replace <faddom-server> with the address of the server you have deployed.

If for some reason you cannot deploy using a URL, you can download the relevant files here and then deploy using the files:

https://<faddom-server>/Installations/Sensors/Template/Faddom-Sensor-Appliance-2021.4.9.ovf

https://<faddom-server>/Installations/Sensors/Template/Faddom-Sensor-Appliance-2021.4.9-disk1.vmdk

When creating importing the Faddom sensor, please ensure it has the VM tag faddom-sensor.
